Environment and safety
Environmental responsibility
Scania develops and produces engines that are as
environmentally-friendly as possible. Scania has
made major investments in the reduction of
harmful exhaust emissions in order to fulfil the
environmental requirements in force in almost
every market.
At the same time, we have been able to maintain
a high level of performance and operating economy for Scania Industrial and Marine Engines.
To maintain these throughout the entire service
life of the engine, it is important for the user to
follow the instructions on running, inspection
and fuel and lubricating oil as outlined in the Operator's Manual.
Other green initiatives taken include ensuring
that, following inspection and repair, waste that
is harmful to the environment (for example oil,
fuel, coolant, filters and batteries) is disposed of
accordance with the applicable environmental
requirements.
Safety
The following pages contain a summary of the
safety precautions to be complied with when operating and inspecting Scania engines. The
equivalent text can also be found under the relevant inspection point.
To prevent damage to the engine and to ensure
that it runs optimally, follow the instructions in
the warnings and advisories.
If the instructions are not followed, the warranty
can cease to apply.

Scania CV AB 2016, Sweden
Environment and safety
Refuelling
Never overfill the fuel tank as the fuel needs
space to expand. Also ensure that the filler cap is
properly closed.
WARNING!
During refuelling there is a risk of fire and explosion. The engine must be switched off and smoking is prohibited.
Hazardous gases
WARNING!
Only start the engine in a well ventilated area.
The exhaust gases contain carbon monoxide and
nitrogen oxides, which are toxic.
If it is run in an enclosed space, there should be
an effective device to extract exhaust gases and
crankcase gases.

start-up in the inspection schedule. See the Inspection section.
Always check the following before running:
• oil level
•coolant
• fuel level
• electrolyte level in batteries
• state of charge of the batteries
• condition of the drive belt.
Checks before running
Carry out a daily inspection as described in the
inspection schedule prior to operation. See the
Inspection section.
WARNING!
Block the starting device when working on the
engine. If the engine starts unexpectedly, there is
a serious risk of injury.
OPM 250 en-GB 20

Scania CV AB 2016, Sweden
Starting and running
Starting the engine
For environmental reasons the Scania engine has
been developed to be started with a low fuel feed.
Using unnecessarily large amounts of fuel when
starting the engine always results in emissions of
unburnt fuel.
• Open the fuel cock if fitted.
• Disengage the engine.
• If the engine has a battery master switch:
Switch on the power by means of the battery
master switch.
• Start the engine.
If the fuel tank has been run dry or if the engine
has not been used for a long time, bleed the fuel
system.
WARNING!
Never use starter gas or similar agents to help
start the engine. An explosion may occur in the
intake manifold with a risk of personal injury.
Only start the engine in a well ventilated area.
When the engine is run in an enclosed space,
there must be effective devices to extract exhaust
gases and crankcase gases.
IMPORTANT!
The starter motor must only be cranked twice for
30 seconds at a time. After that, it must rest for at
least 5 minutes before the next attempt to start it.
Starting at low temperatures
Take the local environmental requirements into
account. Use a fuel heater and engine heater to
avoid starting problems and white smoke.
Scania recommends that an engine heater should
be used if the engine will be used at temperatures
below -10°C.
A low engine speed and a moderate load on a
cold engine limits white smoke, gives better
combustion and warms up the engine more
quickly than warming it up with no load.
Avoid running it longer than necessary at idling
speed.

• Alarm and engine shutdown override control.
Note:
High oil pressure (above 6 bar/87 psi) is normal
when starting a cold engine.
Charging indicator lamp
If the lamp comes on during operation:
• Check and adjust the alternator drive belts as
described under the corresponding inspection
point. See the Inspection section.
If the charging indicator lamp is still on, this
could be due to an alternator fault or a fault in the
electrical system.
Belt transmission
When the belt transmission is new, it may make
a squeaking noise when running. The noise is
normal and disappears after 50-100 hours of operation.
The noise does not affect the service life of the
belt transmission.

Starting and running
Engine shutdown
1. Run the engine without a load for a few min-
utes if it has been run continuously with a
heavy load.
2. Switch off the engine.
Note:
The battery voltage must remain on for a few
seconds after the 15 voltage is switched off so
that the control units can store the values and
switch to standby mode.
10 prohibited engine shutdowns will cause a
torque reduction (70% of fuel quantity). Reset
the engine by switching it off correctly once.
IMPORTANT!
There is risk of post boiling and of damage to the
turbocharger if the engine is switched off without cooling.
The power must not be switched off before the
engine has stopped.
